要約(英語): We analyzed the Hablanian plot results of the welding data using only fiber lasers for stainless steel (SUS304). These data were a part of those in our previous article. We discussed the following: (1) two types of unique behavior confirmed in our previous article, (2) a difference between Hablanian plot and Swift's model, and (3) the prediction of a penetration depth using Hablanian plot with pulsed lasers. The following findings could be derived. (1) Micro welding results located above the standard fitting curve for welding data using CW fiber lasers. This would result from the use of long-focus lenses. (2) The fitting curve for ff = ∼300 mm was the closest to the standard fitting curve. (3) In the higher Vd/K and P/(θtk) regions, the experimentally obtained penetration depth was ∼20% of that without any losses of a laser energy. (4) In order to predict a penetration depth using pulsed lasers, we need to obtain the Hablanian-plotted fitting curves with the corresponding duty ratios.
